Technical Field
[0001] The utility model relates to the field of medical instruments, in particular to a sterile sharps box for PICC puncture. Background Art
[0002] Intravenous infusion therapy is currently one of the main treatment methods for hospitalized patients. Due to the patient's venous conditions, the nature of the drug, etc., the patient needs to have a medium-length catheter or central venous catheter (CVC / PICC / PORT) inserted into the peripheral vein to meet their intravenous infusion requirements. At present, medium-length catheter placement and central venous catheter placement have been widely used in clinical practice. The above two catheter placement processes require strict aseptic operation, and this operation is an invasive operation. During the operation, four materials that produce sharp objects are required: disposable sterile syringes (1ml and 20ml), skin scrapers, puncture needles, and disposable guide wires. However, due to the limitations of the aseptic principle, the operator cannot immediately and standardizedly deal with the sharp objects generated by the operation, so there is a risk of needlestick injuries, sharp injuries, and occupational exposure; and in the preparation process for catheterization, after using a 1ml syringe to aspirate the drug, there is a risk of needle and drug contamination when the needle cap is put back on with one hand.

[0027] Reference below Figure 1 , the utility model is further described as follows:
[0028] A sterile sharps box for PICC puncture, comprising:
[0029] The first storage layer 1 is rectangular in shape and has a storage space inside;
[0030] The second storage layer 2 has the same shape as the bottom surface of the first storage layer 1, is connected to the first storage layer 1, and is in a rectangular shape as a whole, with a storage space provided inside;
[0031] The box cover 3 has the same shape as the bottom surfaces of the first storage layer 1 and the second storage layer 2 and is connected to the second storage layer 2;
[0032] At least one needle cap fixing device 31 is fixedly connected to one side of the box cover 3. During use, the number of the needle cap fixing devices 31 can be adjusted according to usage.
[0033] The first storage layer 1 can be used to place guide wires. Storing the guide wires separately can effectively prevent the guide wires from being contaminated by other sharp objects, and the guide wires can be taken out separately.
[0034] The second storage layer 2 can be used to store used syringes, scrapers, puncture needles, etc. to prevent medical staff from being pricked by needles or scratched by sharp objects, which can effectively reduce the risk of occupational exposure.
[0035] In this embodiment, the first storage layer 1 and the second storage layer 2 are connected in a hinged manner.
[0036] In this embodiment, the box cover 3 and the second storage layer 2 are connected in a hinged manner.
[0037] In an optional embodiment, a spring device is provided inside the needle cap fixing device 31, which can clamp needle caps of various specifications.
[0038] In an optional embodiment, the needle cap fixing device 31 is made of elastic material and can clamp needle caps of various specifications.
[0039] When the medical staff inserts the catheter, after the needle cap of the syringe is removed, the needle cap is placed in the needle cap fixing device 31. After the syringe is used up, the syringe is inserted into the needle cap on the needle cap fixing device 31, avoiding the traditional one-handed sheathing operation and the risk of medical staff being stabbed.
[0040] In an optional embodiment, the rotation angle range of the second storage layer 2 relative to the first storage layer 1 is 0° to 180°, and medical staff can freely select the opening and closing angle according to usage needs.
[0041] In an optional embodiment, the rotation angle range of the box cover 3 relative to the second storage layer 2 is 0° to 45°. Within this angle range, the position of the needle cap fixing device 31 is more convenient for medical staff to perform the needle cap re-covering operation.
[0042] In an optional embodiment, a limiting device is provided between the box cover 3 and the second storage layer 2. When the box cover 3 is opened at an angle of 45° relative to the second storage layer 2, the limiting device can clamp the box cover 3. At this time, the needle cap fixing device 31 is located above the second storage layer 2. After the medical staff performs the needle cap re-sheathing operation, due to the effect of gravity, the syringe and the needle cap fall into the storage space of the second storage layer 2 together.
[0043] In this embodiment, a first switch 11 is provided on one side of the first storage layer 1 for controlling the opening and closing between the first storage layer 1 and the second storage layer 2. When the first storage layer 1 needs to be opened, it is only necessary to press the first switch 11 and then flip the second storage layer 2 upwards.
[0044] In this embodiment, a second switch 21 is provided on one side of the second storage layer 2 for controlling the opening and closing between the second storage layer 2 and the box cover 3. When the second storage layer 2 needs to be opened, the second switch 21 only needs to be pressed, and then the box cover 3 is flipped up.
[0045] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0046] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0047] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
[0048] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
